Half-size battery?

I searched but came up with nada...

I'm looking for someplace that sells those half-size batteries..

They look like an Optima YellowTop but are half the width.

My accessory drive just about chewed through my stocker so I'm trying to find a solution ASAP... my KOYO ended up getting in the way of the tray so my ghetto solution to get me to work was to stick a DVD case underneath... it was a bad idea I know.

Thanks in advance,
~Kris

I think you are looking for a battery size 51R.

All the small size ones I see there are meant for watercraft/motorcycles, they dont look like they produce enough CCA. I may just be looking at the wrong models, do you have a direct link to the battery?

Thank you,

JaNusSolSumnus,

The Optima 51R should fit just fine (as long as you didn't up-right the radiator). I also believe that TurboJeff has one or two Battery Trays left.

There is a lot of info on this in the forum. Do a search on Optima and/or Odyssey batteries. Personally I have heard some bad stuff on the Optima brand. I've been running a Hawker 925 with 470 CCA for 4 to 5 years now with no problems. I have info on my site.

The 925 is the way to go. Half the size & weight. 4+ years with no problems.

True that. Hawker is the company name while Odyssey is the battery name. Kind of like "Mazda" "Rx-7".

BTW nice tray Sled Driver!

First, buy this battery from www.batterymart.com for $86.00



Then buy the battery mount from www.summitracing.com for $40.00 part number ODY-HDB680.




Alternatively, try the Hawker PC925 for $105



With this holder for $110.00 at summitracing part ODY-HDB925

I picked up a 51r today at Autozone.... my stock battery was just about chewed through and my having to drive to work forced me to do stupid actions like that.

I'll PM TurboJeff and order his tray if he has some left. I am really happy with the size of the Optima, it was indeed the correct one I was after.

Thank you all,
~Kris

PC680 works just fine for the 7 as there is not that much rotational mass. With the battery tray that Chuck sells at Rotary Extreme it is a great set up.

That's weird, I just went to my local auto zone, and they said they 1) Don't carry and 2) can't order the 51R. I told them people had been getting them at other Auto Zone's in other parts of the counrty, but he didn't believe me.


Anyone know where I can pick up a 51R locally?

Thanks for the tip. I just got back from Sears looking for a DieHard unit, but found out that they sell Optima batteries there, and had a 51R so I picked that up. Going to go install the TurboJeff battery tray and 51R now.

Which 51R is suggested ? there are all kinds of different brands from regular battery's to deep cycle optima 51R , since the battery is smaller Should we go for a deep cycle 450 CCA one ( optima ) , or a 500 CCA ( regular high quality battery )

RISE FROM THE DEAD!

On batteries, just get a good brand of battery from a local auto parts store. I don't think it's worth the money for the Optima batteries. The RX-7 isn't some magic car when it comes to batteries, a battery is a battery.

At least he searched before posting... *claps*

I would not suggest an optima based on what people I know and the troubles they've had

Like Dale said no 'special' battery is needed, although I did go with one the same size as the odyssey 925, and it works perfectly, and still small enough to be shoved in odd places...

Fwiw, my Odessey 925 lasted 8 yrs--hard to beat that. Going to replace it with another one.

No experience with the other batteries but my 51R w/Turbojeff tray has served me well and opened up space in the engine bay. Turbojeff's battery tray is a must have as it secures the battery properly and is a very well made product.
